Title: Photodiode array fourier transform spectroscope
Inventor: MATSUDA JOJI
IPC: G01J3/45
Filed: 1986-12-13
Abstract: PURPOSE:To enhance resolving power while high throughput and stability are held, by arranging a moire lattice in the beam path between an interferometer and a photodiode array detector. CONSTITUTION:The beam from a beam source 2 is converted to parallel luminous flux by a lens 3 to be incident to an interferometer 4 consisting of a beam splitter B and mirrors M1-M3. The lens 5 projects the interference fringe of the virtual image formed on the surface of the mirror M2 on the surface of a moire lattice 6. Hereupon, a fringe interval is adjusted on the basis of the inclination of the mirror M2 around the vertical axis thereof by the interferometer 4. The mirror M1 or M3 is inclined around a horizontal axis and the contrast of the fringe is adjusted by utilizing the spatial coherence of the beam source 2. The interference fringe on the surface of the lattice 6 is erased by the inclination of the mirror M1 and the measurement and operation of background noise become possible. By this method, the SN ratio of a spectrum is improved. A photodiode array detector 8 detects the difference between the frequencies of heterodyne interference fringes led out from the fundamental frequency of the lattice 6.

Abstract: PROBLEM TO BE SOLVED: To obtain an digital image of the eyes to be examined by using a general purpose digital camera with an inexpensive, smaller and simple structure. SOLUTION: Retinal reflected light by a focusing light source 24 is separated into two luminous fluxes to be taken by a video camera 37 and a separation interval between the two luminous fluxes is computed by an arithmetic means to calculate a diopter of eyes E to be examined. As a result, a focus lens 25 is driven to be adjusted and driven to a determined focus position and the power of a field lens 20 is altered so that the conjugate position of pupils serving as stop of a first image formation optical system forms an image in a second image formation optical system 31 or near it. This enables positioning and focusing and when an examiner depresses an imaging button 9, the resulting signal drives a relay 11 through a body part 1 and an adaptor 3, whereby a shutter 10 of a digital camera 7' is depressed.  When the digital camera 7 is made ready for imaging. a strobe light source 16 emits light and a retinal image is projected onto an image sensor 32 to be stored into a built-in memory by the digital camera 7 while being shown on a display member 33. An examining person views the retinal image to judge the quality of the retinal image.

Title: Bearing
Inventor: MIYAKE HIROSHI
IPC: F16C33/00
Filed: 1986-12-16
Abstract: PURPOSE:To prevent the seizure of a bearing, by fixing a ceramic support plate between the two-divided surfaces of an oil impregnated sintered body, and bringing the oil existing between them into action in a liquid lubricating condition soon after the rotation of a turning shaft. CONSTITUTION:On both sides of an oil impregnated sintered body 1 in the same direction as a turning shaft 2, cutouts are provided, and further the body 1 is divided into two parts at its center so as to be perpendicular to the turning shaft 2. Between the two surfaces divided into two parts, a ring-shaped support plate 6 whose material is ceramics is insertedly fixed. When the turning shaft 2 starts to rotate, while it is lubricated by the oil between the turning shaft 2 and a support part 7, due to the temperature rise caused by the rotational friction at the support part 7, the oil in the oil impregnated sintered body 1 moves to the support part 7 of the support plate 6. Accordingly, soon after the rotation of the shaft, oil is absorbed into the interior of the oil impregnated sintered body 1 from oil reserving parts 3, and further it is drawn out into the support plate 6, thus the seizure of the bearing can be prevented.

IPC: G11B20/18
Filed: 1989-11-16
Abstract: PURPOSE:To eliminate re-reading and to speed up reading by deciding and storing an address to be read next when the reading of the address is judged to be successful, comparing the addresses whenever the address is read and defining it to be an accurate content. CONSTITUTION:A read means 2 reads the address and data of a sector in a recording medium 1. When a judgment means 3 judges that the reading of the having read address is successful, an address counting means 4 decides and stores the address which the means 2 has to be read next based on the address. Then, a comparison means 5 compares the address which the means 4 stores whenever the means 2 reads the address. When they coincide, a data decision means 6 decides that the having read address is the accurate contents. Consequently, a processing operation for re-reading is eliminated even if reading is failed and a read speed can be improved.
